Hi Kamal, I will not answer to your question, but actually I am working on a similar configuration, and I have an issue as described on the following thread [1].
Long story short, when I standby a node (crm node standby) then put it online again my drbd device goes into a split-brain state. Have you this issue? Which distrib and pacemaker/corosync/drbd versions do you use?
